The UFC’s year-end fight card continues to fill up following the addition of a welterweight bout between Bobby Voelker (24-10 MMA, 0-2 UFC) and William Macario (6-1 MMA, 0-1 UFC).

UFC officials today announced the bout.

UFC 168 takes place Dec. 28 at MGM Grand Garden Arena in Las Vegas. The main card airs on pay-per-view following prelims on FOX Sports 1 and Facebook.

Voelker vs. “Patolino” likely will be part of the prelims.

Voelker, though entertaining, is likely in a must-win situation. After a productive 4-1 stint in Strikeforce, the 34-year-old Kansan was moved to the UFC. However, he’s since suffered a decision loss to Patrick Cote and a recent knockout loss (via head kick) to vet Robbie Lawler. He now needs to avoid a third consecutive defeat.

Macario, meanwhile, looks for his first official UFC win after a runner-up finish on “The Ultimate Fighter: Brazil 2,” where he suffered a submission loss to Leonardo Santos in the tourney final earlier this year. Prior to his time on the show, the 22-year-old Brazilian went 6-0 with six stoppages (five knockouts) while fighting throughout his home country.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
